of a whitifh afh colour, in which there is no or- 
ganization, either without or within. However, 
in eight or ten days more, organization is fenfible

ed in fuch a manner, that, unlefs from the lighter 
colour, it is not diftinguifhable from the old one. _ 
This, befides external infpeCtion, is demonftrated 
by anatomy. When the new head is laid open, 
the fame parts are feen, correfponding in num. 
ber, figure, and fize, to thofe pre-exifting in the 
old, which were fcrupuloufly egumerated in my 
journal of each decollation. I cannot convey a
